Description. Male . COLORATION ( Fig. 7 ). Greenish-yellow, naturally pale green. Head: Uniformly pale; antenna pale yellow, first segment pale brown, with pale base and apex, rarely pale yellow with incomplete pale brown ring medially; second segment with dark brown ring proximally and brown to pale brown ring distally, middle one-third and extreme apex of second segment pale yellow, third and fourth segments pale brown; labium with darkened apex of fourth segment. Thorax: Pronotum and thoracic venter uniformly pale. Legs : Pale yellow, with narrow pale brown stripe along fore margin of all or at least hind femora, bases of all tibiae dorsally dark brown, brown tibial spines, and entirely or distally darkened tarsi. Hemelytra : Uniformly pale except membrane; membrane smoky pale brown, semitransparent, with brown to dark brown, contrasting, narrow transverse stripe passing from apex of cells through outer margin of membrane distal to apex of cuneus; veins as well as areas proximal and distal to transverse stripe whitish. Abdomen: Uniformly pale. SURFACE AND VESTITURE. Dorsum smooth, shiny, with dense, dark, simple setae, semiadpressed to erect on head and apical part of pronotum, adpressed elsewhere; legs and antennae with similar setae twice as short as those on pronotum and hemelytra; tibial spines slightly longer than width of tibia; first antennal segment with two spine-like setae on medial surface; venter with scarce, silver, adpressed, simple setae. Figs. 18-24. Macrotylus subattenuatus sp. nov. , genitalia and tarsus. 18-19 – vesica (18 – lateral view, 19 – ventral view); 20 – right paramere; 21 – left paramere; 22 – apex of theca; 23 – pretarsus; 24 – claw. Scale bars = 0.05 mm. STRUCTURE: Elongate-oval, total length 1.7-2.1, body 2.9-3.3 × as long as width of pronotum. Head: Moderately projecting anteriorly, clypeus visible from above; vertex 2.0-2.5 × as wide as eye; second antennal segment 0.6 × as long as basal width of pronotum, 0.9 × as long as width of head; labium slightly or substantially surpassing hind coxa, never reaching genital segment. Thorax: Pronotum 2.5-2.6 × as wide as long, with indistinctly demarcated calli; tarsus with somewhat incrassate third segment ( Fig. 24 ), claw as in Fig. 23 . Figs. 25-31. Macrotylus attenuatus Jakovlev, 1882 , genitalia and tarsus (Turkey: Kayseri). 25 – vesica, lateral view; 26 – vesica, ventral view; 27 – right paramere; 28 – left paramere; 29 – apex of theca; 30 – pretarsus; 31 – tarsus. Scale bars = 0.05 mm. MALE GENITALIA. Genital capsule: About 40 % of abdomen, without distinctive ornamentation. Parameres: Shape typical for Phylini , right paramere as in Fig. 20 , left paramere as in Fig. 21 . Apex of theca: As in Fig. 22 . Vesica: C-shaped, with uniformly sclerotized strap along lateral margins, posterior (in lateral view) flange of vesical strap wide extended beyond curvature of anterior flange ( Figs. 18-19 , indicated with asterisk); secondary gonopore subapical, located just proximal to short, straight, almost triangular, in ventral view, apical blade. Female. COLORATION, SURFACE AND VESTITURE. As in male. STRUCTURE. As in male, with similar body proportions. Total length 1.9-2.1, body 2.9- 3.4 × as long as width of pronotum. Head: Vertex 2.2-2.9 × as wide as eye; second antennal segment 0.6 × as long as basal width of pronotum, 0.8-0.9 × as long as width of head. Thorax: Pronotum 2.3-2.7 × as wide as long. Differential diagnosis. Recognized by the small body size, color-pattern of antennae, darkened bases of tibiae, narrow transverse band on membrane behind cells, C-shaped vesica with straight apical blade, and extended posterior flange. The new species closely related to and virtually indistinguishable from Macrotylus attenuatus Jakovlev, 1882 in the body proportions, vestiture, color-pattern ( Fig. 8 ), structure of tarsus ( Figs. 23-24 ) and other characters of external morphology, as well as in the structure of theca ( Fig. 22 ), and parameres ( Figs. 20-21 ). Both species associated with Potentilla spp. (Rosaceae) . Macrotylus attenuatus somewhat differs from the new species in the larger average size (Table 1) and vestiture of third and fourth antennal segments, with longer semierect setae, exceeding the width of respective segments. Clearly separated from M. subattenuatus sp. nov. by the structure of comparatively thin, Jshaped vesica, with longer, gradually curved apical blade, and posterior flange of vesica not exposed in lateral view (marked with asterisk on Figs. 25-26 ). Etymology. The species name ‘ subattenuatus’ indicates that the new species is nearest to M. attenuatus . Host plant. Potentilla sp. (Rosaceae) . Distribution. North Kazakhstan , Akmola province.
